Thermoeconomical optimization of a regenerative air turbine cogeneration system

The concept of optimization operating and design parameters the regenerative air turbine cogeneration (RATC) system is proposed. To determine energy efficiency indicators this system, its thermodynamic analysis was performed. At same time, it shown that not correct to search for optimal such a only by indicators, modern thermoeconomic methods should be more actively involved in pre-design practice, which allow comprehensive evaluation economy energy-technological as whole individual elements. Therefore, on basis data obtained during analysis, exergy destruction losses main elements were calculated. Then, using structural-variant method combination with graphical apparatus C-curves, pre-project RATC This made possible choose minimum cost creation operation throughout entire life cycle, taking into account perfection Each variable mode parameter serves kind navigator when searching option terms economic accompanied graphic visualization. proposed approach makes being designed convenient clear. It can used various types thermal transformers other systems.
